Title:
ウレタン−イソシアヌレートを作製するための方法
Document Type and Number:
Japanese Patent JP6383404
Kind Code:
B2
Abstract:
Polyisocyanurate or polyurethane-isocyanurate polymers are made by curing an aromatic polyisocyanate or a mixture of at least one aromatic polyisocyanate and at least one polyol having a hydroxyl equivalent weight of up to 200 in which the isocyanate index is at least 2.00, in the presence of at least one isocyanate trimerization catalyst, to form a polyisocyanurate or polyurethane-isocyanurate polymer having a glass transition temperature of at least 100° C., and then exposing the polyisocyanurate or polyurethane-isocyanurate polymer formed step a) to water under superatmospheric pressure at a temperature of at least 70° C.
